Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer substations, in particular to a new energy box-type transformer substation with shock absorption treatment. BACKGROUND

[0002] As a complete power distribution device that organically combines high-voltage power receiving, transformer voltage reduction, and low-voltage power distribution functions, the box-type transformer substation has the advantages of compact structure, small footprint, low investment, and convenient installation, and is widely used in urban power grids, industrial and mining enterprises, communities, and public facilities. The new energy industry represented by wind energy and solar energy is developing rapidly, and the demand for box-type transformer substations, which are key power transmission and distribution equipment for new energy power generation systems such as wind farms and photovoltaic power stations, is increasing day by day.

[0003] However, new energy power generation sites often have special environments, such as remote locations, coastal mudflats, and Gobi deserts, which make the traditional box-type transformer substation face many severe challenges in actual operation. First, in terms of mechanical vibration, the problem is particularly prominent. The excitation inrush current of the high-capacity transformer inside the box-type transformer substation and the load change itself will produce continuous power frequency vibration, which is an inherent technical problem. External environmental factors are more complex and diverse: the low-frequency vibration produced by the operation of wind turbine generators will be transmitted to the box through the foundation structure; the operation of large construction machinery in the surrounding area will bring strong impact vibration; the box-type transformer located along the road also has to withstand continuous microseismicity caused by vehicle traffic for a long time. These vibrations often have the characteristics of multi-directionality and composite frequency, and a single shock absorption measure is difficult to effectively cope with. Continuous vibration and impact not only produce annoying operating noise, but also cause the bolts of the box structure to loosen, the welded joints to fatigue and crack, and the connection points of internal electrical components (such as circuit breakers, wiring terminals, and control modules) to loosen, contact poorly, or even insulation damage, which seriously threatens the electrical safety and service life of the equipment.

[0004] In addition, the existing shock absorption measures have obvious shortcomings. The most common method at present is to install rubber pads between the box and the foundation. This simple passive shock absorption method has many limitations: first, it has poor low-frequency vibration absorption effect and slow attenuation, especially for the low-frequency vibration produced by wind power equipment, which is almost impossible to effectively isolate; second, the rubber material is prone to aging, and its elastic properties and shock absorption effect will decrease significantly after being exposed to environmental influences such as ultraviolet light, ozone, and temperature changes for a long time outdoors, and it usually needs to be replaced after 3-5 years, resulting in high maintenance costs. SUMMARY

[0005] The purpose of the present application is to provide a new energy box-type transformer substation with shock absorption treatment to solve the problem of poor shock absorption performance in the prior art.

[0006] In order to achieve the above object, the present application provides the following technical scheme: A new energy box-type substation with damping treatment, comprising a substation box, wherein the substation box is internally provided with a plurality of electrical elements, and further comprising a mounting frame, wherein both sides of the mounting frame are internally provided with mounting grooves, both the mounting grooves are internally provided with connecting plates which are slidably installed, and both the connecting plates are respectively connected with both sides of the substation box.

[0012] Further, a support is installed on one side of the substation box, sliding grooves are formed on both sides of the support, a lifting plate is slidably installed in the sliding grooves, and a sealing plate is installed on the upper end of the lifting plate.

[0013] Further, telescopic elements are installed on both sides of the support, and the output ends of the telescopic elements are connected with the upper end of the lifting plate.

[0014] Further, a slide is installed on one side of the support, a lead screw is rotatably installed in the slide, a sliding plate is slidably installed in the slide, a threaded ring is internally provided in the sliding plate, and the threaded ring is threadedly connected with the lead screw.

[0015] Further, a support plate is installed on one side of the sliding plate, a cleaning brush is installed on one side of the support plate, and the cleaning end of the cleaning brush is in contact with the working surface of the dustproof net.

[0016] Further, a transmission element is installed in the slide, and the output end of the transmission element is connected with the lead screw.

[0017] Compared with the prior art, the new energy box-type substation with damping treatment has the following beneficial effects.

[0018] The present application can absorb, buffer and dissipate vibration energy from all directions through the damper and the shock-absorbing elastic piece.

[0019] The present application realizes the automatic start-stop of the heat dissipation system through real-time processing of temperature sensor data by the central processing unit.

DETAILED DESCRIPTION

[0028] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0029] As shown in the accompanying Figure 1 to the accompanying Figure 5 drawings:

[0030] Example 1:

[0031] The present application provides a new energy box-type substation with shock absorbing treatment, comprising a transformer box 1, the transformer box 1 is internally provided with a plurality of electrical components 2, further comprising a mounting frame 6, the mounting frame 6 is internally provided with mounting grooves 7 on both sides, two mounting grooves 7 are internally slidably provided with connecting plates 8, two connecting plates 8 are respectively connected to both sides of the transformer box 1.

[0032] A damper 9 is installed at the lower end of the transformer box 1 and the lower end of the mounting frame 6, and the outer surface of the damper 9 is provided with a shock absorbing elastic member 10, the shock absorbing elastic member 10 is a high-performance shock absorbing spring, and the damper 9 is a hydraulic damper.

[0033] The upper end of the transformer box 1 is internally provided with a central processing unit 3, a temperature sensor 4 and a smoke sensor 5.

[0034] Working principle: when the box-type substation is vibrated or impacted due to external environment such as vehicle passing, crustal micro-motion or internal equipment operation such as transformer working vibration, the vibration energy is first transmitted through the mounting frame 6. The transformer box 1 forms a sliding fit with the mounting grooves 7 on both sides of the mounting frame 6 through the connecting plates 8 connected on both sides. This makes the transformer box 1 can have limited relative displacement in the vertical direction relative to the mounting frame 6, instead of rigidly bearing all the impact.

[0035] In this process, the damper 9 and the shock-absorbing elastic element 10 between the lower end of the transformer box 1 and the lower end of the inside of the mounting frame 6 begin to play a role. The shock-absorbing elastic element 10 absorbs and stores most of the shock kinetic energy through its elastic deformation, acting as a buffer. The damper 9, which works in conjunction with it, converts the absorbed kinetic energy into heat energy and dissipates it through the friction or throttling of its internal medium, thereby effectively suppressing the reciprocating oscillation of the shock-absorbing elastic element 10 when it rebounds, rapidly attenuating the shock, and quickly restoring the transformer box 1 and its internal electrical components 2 to a stable state. This dual shock-absorbing mechanism greatly reduces the risk of damage to precision electrical components 2 from continuous vibration, extending the service life of the equipment.

[0036] Through the damper 9 and the shock-absorbing elastic element 10, the shock energy from all directions can be absorbed, buffered, and dissipated. This reduces the risk of stress damage, loosening, and even failure of electrical components 2 such as circuit breakers, control modules, and transformers inside the transformer box 1 caused by continuous vibration and transient impact, fundamentally improving the operational reliability and service life of the equipment. At the same time, it can effectively deal with various vibration sources, including but not limited to continuous microseismicity caused by road traffic, impact from nearby construction, and power frequency vibration from internal transformer operation, making the box-type substation particularly suitable for complex outdoor environments such as highways, wind farms, and photovoltaic power stations.

[0037] Moreover, the inside of the transformer box 1 is in a state of real-time intelligent monitoring. The temperature sensor 4 arranged at the upper end of the inside of the transformer box 1 continuously monitors the temperature data of the key areas inside the box, and the smoke sensor 5 monitors whether there are smoke particles generated due to electrical short circuit, overheating, etc.

[0038] These sensors transmit the collected real-time data to the central processor 3 also located at the upper end of the inside of the box. The central processor 3, as the control center, has pre-set safety thresholds for temperature and smoke concentration. Once the collected data exceeds the safety threshold, the central processor 3 can determine that it is an abnormal state such as overheating or fire hazard, and immediately start the predetermined alarm program. The alarm methods can include but are not limited to: starting the on-site sound and light alarm, sending alarm signals to the remote monitoring center, etc., thereby achieving early detection and warning of faults, allowing maintenance personnel to take measures to gain valuable time, prevent accidents from expanding, and ensure the safety of the power grid.

[0039] Embodiment Two:

[0040] This embodiment is basically the same as the previous embodiment, with the difference being that it includes a transformer box 1, and the inside of the transformer box 1 is provided with a plurality of electrical components 2.

[0041] The inside of the transformer box 1 is provided with a central processor 3, a temperature sensor 4, and a smoke sensor 5 at the upper end.

[0042] The transformer box 1 is provided with a ventilation opening 11 on one side, and a heat dissipation member 12 is arranged on one side of the ventilation opening 11.

[0043] The heat dissipation member 12 comprises a fixing frame 121 arranged on one side of the inside of the transformer box 1, a driving member 122 is mounted on one side of the fixing frame 121, a rotating shaft 123 is rotatably arranged in the fixing frame 121, a plurality of blades 124 are uniformly arranged on the outer surface of the rotating shaft 123, and the driving member 122 is an electric motor.

[0044] The dustproof net 13 is mounted at the front end of the ventilation opening 11.

[0045] The transformer box 1 is provided with a support 14 on one side, sliding grooves 15 are arranged on both sides of the support 14, a lifting plate 16 is slidably arranged in the sliding grooves 15, and a sealing plate 17 is mounted on the upper end of the lifting plate 16.

[0046] The support 14 is provided with an extension member 18 on both sides, the output end of the extension member 18 is connected to the upper end of the lifting plate 16, and the extension member 18 is an electric telescopic rod.

[0047] Working principle: The temperature sensor 4 arranged at the upper end of the inside of the transformer box 1 continuously monitors the temperature of the inside of the box and transmits the data to the central processor 3 in real time, the central processor 3 compares the received temperature data with the preset safety threshold value, when the temperature exceeds the threshold value, the central processor 3 determines that the heat dissipation program needs to be started, and sends a start instruction to the driving member 122 of the heat dissipation member 12, after the driving member 122 is started, the rotating shaft 123 is rotated, and then the plurality of blades 124 mounted thereon are rotated. The airflow generated by the blades 124 is extracted from the inside of the box through the ventilation opening 11, and at the same time, the external cold air is sucked in, so as to realize the convection heat exchange and effectively reduce the temperature in the box. During the whole ventilation process, the dustproof net 13 mounted at the front end of the ventilation opening 11 effectively intercepts the dust, willow catkins and other sundries in the external air, so as to prevent the sundries from entering the box and polluting the electrical components 2 or affecting the heat dissipation efficiency.

[0048] When the temperature sensor 4 detects that the temperature is normal, the central processor 3 can control the extension member 18 to be in an expanded state. The output end of the extension member 18 pushes the lifting plate 16 downward, and drives the lifting plate 16 connected thereto to slide downward along the sliding groove 15 on the support 14. The lifting plate 16 moves downward to drive the sealing plate 17 thereon to descend until it completely covers and seals the ventilation opening 11. This state can effectively prevent rainwater, moisture and even external sundries from entering the box through the ventilation opening 11, and ensure the safety of the internal electrical components.

[0049] When the temperature inside the box rises to the point where heat dissipation is needed, the central processor 3 sends an extension command to the telescopic part 18 before starting the drive 122 of the heat dissipation part 12. The output end of the telescopic part 18 retracts, driving the lifting plate 16 to slide upward along the sliding groove 15, thereby lifting the sealing plate 17 and opening the ventilation opening 11 to provide a channel for air cooling.

[0050] Through real-time processing of temperature sensor 4 data by central processor 3, automatic start and stop of the heat dissipation system is achieved. The opening of the heat dissipation channel ventilation opening 11 and the start of the heat dissipation part 12 are controlled in linkage, ensuring maximum heat dissipation efficiency, effectively preventing damage to the electrical components 2 inside the box due to overheating, ensuring continuous and stable operation of the equipment, and avoiding energy waste caused by traditional continuous ventilation cooling. At the same time, accurate temperature control avoids long-term operation of components in high-temperature working conditions, effectively prolonging the service life of the electrical components 2 and the heat dissipation part 12 itself, and reducing the overall operation and maintenance cost. Secondly, the sealing plate 17 structure driven by the telescopic part 18 can completely close the ventilation opening 11 during the non-heat dissipation period. This design effectively isolates the intrusion of external rainwater, moisture, salt mist and dust, greatly reducing the risk of corrosion, short circuit or pollution of internal components, and significantly improving the long-term reliability of the box in harsh outdoor environments such as rainy and dusty areas.

[0051] Embodiment Three:

[0052] This embodiment is basically the same as the previous embodiment, the difference is that it includes a transformer box 1, the transformer box 1 is internally provided with a plurality of electrical components 2, and the transformer box 1 is internally provided with a central processor 3, a temperature sensor 4 and a smoke sensor 5 at the upper end.

[0053] One side of the transformer box 1 is provided with a ventilation opening 11.

[0054] A dust screen 13 is installed at the front end of the ventilation opening 11.

[0055] One side of the bracket 14 is provided with a sliding channel 19, a lead screw 20 is rotatably installed inside the sliding channel 19, a sliding plate 22 is slidably installed inside the sliding channel 19, and a threaded ring is provided inside the sliding plate 22. The threaded ring is in threaded connection with the lead screw 20.

[0056] One side of the sliding plate 22 is provided with a support plate 23, and the support plate 23 is provided with a cleaning brush 24 on one side. The cleaning end of the cleaning brush 24 is in contact with the working surface of the dust screen 13.

[0057] A transmission part 21 is installed inside the sliding channel 19, the output end of the transmission part 21 is connected with the lead screw 20, and the transmission part 21 adopts a stepping motor.

[0058] Working principle: when the central processing unit 3 judges that the heat dissipation efficiency is reduced according to the data of temperature sensor 4, the fan has worked for a period of time, but the temperature drop does not reach the expected value, it can be inferred that the dust screen 13 may be blocked, and then the cleaning program is started, when the cleaning program is started, the central processing unit 3 sends instructions to the transmission member 21, the transmission member 21 is started, and the output end drives the screw rod 20 to rotate, because the sliding plate 22 is engaged with the screw rod 20 through the internal thread ring, and the sliding plate 22 is limited in the slide 19 and can only slide, therefore the forward and reverse rotation of the screw rod 20 will be converted into the reciprocating lifting movement of the sliding plate 22 along the slide 19, the sliding plate 22 drives the support plate 23 and the cleaning brush 24 installed thereon to move together, the bristle end of the cleaning brush 24 always keeps contact with the outer surface of the dust screen 13. In the reciprocating movement process, the bristles can scrape and clean the dust, willow catkins and other sundries attached to the outer surface of the dust screen 13, so that the dust screen 13 restores the ventilation capacity, and completes a cleaning cycle. After one reciprocating movement, the transmission member 21 stops working, and the cleaning brush 24 usually stays at the initial position on one side, waiting for the next instruction.
